Neither should it have "a heap of conectors".
So, what actualy happened is rather than cut one wire on the PGM-III (the wire splice), what someone had done is cut a whole load and spliced in part of the HRC mc21 loom.
The loom and a few other bits (jet kit, airbox) are part of the SS/SP racing kit and aren't really that rare.

The rare stuff is the F3 stuff, the F3 PGM-II, loom, crank, stator, cases etc. In general these can be identified by the fact they don't fit/work on their own and they don't have KV3 in the part number.
